Abstract
The optimal single line compensating model is presented and analysed for short 1000-kV UHV parallel lines, to limit secondary arc current and recovery voltage. According to this study, for perfectly transposed 1000-kV lines shorter than 183 km, 750-kV parallel lines shorter than 280 km and 500-kV parallel lines shorter than 500 km, the secondary arc current can be compensated in single line model, and hence achieving the successful selective pole reclosing. Simulations on real time digital simulator (RTDS) have been carried out to evaluate the compensation scheme proposed in this study.
